Venn diagrams and sets · Grade 10

In Grade 10 you learn: sets and Venn diagrams.

A Venn diagram sorts things into overlapping circles inside a rectangle. The rectangle is the universal set ξ. The diagram makes it easy to count the items in one group, in both, in either or in neither. It also helps you find probabilities.

Key facts

• A′ (complement): not in A.
• Fill in a Venn diagram from the middle (the overlap) outwards.
